Friendly and efficient service at the telephone and the collar really helps with lead control. It hasn’t stopped pulling but it makes lead walking our rescue springer a lot more manageable whilst we are training and working towards loose lead walking.
We have a strong 16 month old female labrador. She's a great dog but can pull. The Canny collar does reduce pulling although she doesn't particularly like but she will tolerate it and it clearly doesn't hurt her. Another advantage is the nose band is easily removed to act as a normal collar.
Bought the collar and lead on the recommendation of a complete stranger in the park who saw me really struggling with my young sighthound as she'd been through the exact same thing with hers as a younger dog. It isn't a panacea for behavioural issues but it's an amazing training aid. We no longer have to muzzle our dog and we can get him under control so much easier when he tries to bolt at another dog. Walking him is something we can look forward to now rather than feeling like a chore and now people love coming up to say hi to our little friendly guy instead of keeping their distance from him like they had to before.
